@Snarf Zagyg has spent reems of e-paper arguing that Greyhawk needs a new book to promote visibility. If the setting is to have players that aren't drawing pensions, a new book is needed to get it out in the public's consciousness again. I agree. After 30 years, how many people even remember Birthright was ever a setting, let alone played it? However, there is no way WotC isn't going to make changes to it. So we have the terms.
Imagine if, as part of the 1D&D project, WotC announced they would focus on only new settings. No classic settings, just new worlds and MTG conversions. The lore of Greyhawk would be preserved forever at whatever point you want (Folio, From the Ashes, LGG). Never to see an update again. Would that make you happy? It does
@Micah Sweet . He's said better dead than retread. Is the preservation of lore worth the setting increasingly played by a dwindling group of aging players? People have already lamented that more people know Exandria than Oerth, I can't imagine what 5 years of new settings would do to the institutional memory of the TSR era settings.
So to all those people who would rather see a setting die than change, be careful what you wish for. In ten years, you might sit down next to a player who has never heard of Greyhawk and thinks it is as antiquated as downwards AC...
